It was a VERY long time ago (1977) that we visited Montserrat. However, I still have a copy of our itinerary and notes (we're talking pre-computer days) from that month long drive through Spain and Portugal. (Even I can hardly believe that I still have that stuff!) We stayed at...Hostal Abad Cisneros where a double room with breakfast, dinner and drinks cost us 2348 pesetas (at 82.8 pesetas to the dollar, it was a steal even then). I haven't checked on-line to see whether this particular hostal is still in business but I do have a copy of Rick Steves' book which recommends staying overnight in the old monks' quarters (twin--7580 ptas, fine restaurant attached). It was such a wonderful experience.
